3 Claims.

This invention relates to a mobile ground working device, such as ashovel, plow or cultivator, more particularly to a combined adjustablesuspension and traction means for each side of the body-part or frame ofthe device and is a continuation in part of our application filed June1, 1935, Serial Number 24,553, new Patent No. 2,029,249, dated Jan. 28,1936.

The invention has for its object to provide, in a manner as hereinafterset forth, an adjustable suspension and traction structure for each sideof the body-part or frame of a mobile ground working device includingtraction elements carried by suspensions and with the latter capable ofbeing adjusted for elevating and lowering the said bodypart or framerelative to the ground, and with said suspensions connected to andwithin said body part and extended outwardly and depending from thesides of the latter.

further object of the invention is to provide, in a manner ashereinafter set forth, a suspension means for the purpose referred toand with the traction elements carried by said means being oi thecushioned type.

it further object of theinvention is to provide, in a manner ashereinafter set forth, a mobile ground working device of that typeincluding a skeleton body part or frame carrying ground working toolsand with the device, at its sides, having vertically adjustable combinedsuspension and traction means therefor capable of being I adjusted forthe purpose of elevating and lowering the body-part or frame of thedevice relative to the ground, as well as providing a cushioned sup portfor the device especially when the latter is traveling and acting on theground.

Further objects of the invention are to provide, in a, manner ashereinafter set forth, a vertically adjustable combined cushionedsuspension supand traction means for the purpose referred to which issimple in its construction and arrangement, strong, durable, compact,conveniently installed with respect to the sides of the bodypart orframe of a mobile ground working device, readily adjusted when occasionrequires, and inex pensive to manufacture.

With the foregoing and other objects which may hereinafter appear, thisinvention consists of such parts and such combination of parts, as willbe more specifically referred to and are as illustrated in theaccompanying drawing wherein is shown embodiments of the invention, butit is to be understood that changes, variations and modifications may beresorted to which fall within the scope of the invention as claimed,

Figure 6 is a fragmentary view partly in sec tion illustrating amodification of the cushioned combined suspending, supporting andtraction structure;

With reference to Figures 1 to 5 of the drawing, 2d the ground workingdevice is shown as including a horizontally disposed rectangular bodypart or frame l hereinafter termed a skeleton body. The latter is formedof a set of spaced parallel I-beams t arranged tandemwise and a pair ofoppositely disposed inwardly opening channel irons 9 which overlap theends of the l-beams and are fixedly secured to these latter by the holdfast means it. The beams and irons coact to provide a rectangularskeleton body or frame. 8 Each channel iron, in proximity to its forwardend, is formed with an opening ii. The web i2 of the forward li-beam ofthe set adjacent each end thereof is formed with a pair of superposedopenings it. The body '5 has secured thereon spaced reinforcing means asindicated at i i, 55 and i5 and which constitute a draw-bar provided bythe means 65 and a pair of braces for the drawbar provided by the meansii, iii. The construction, arrangement, description and purpose of themeans it, it and it will be found in our co-p-ending applications,Serial Number 24,553, filed June 1, i935, and Serial Number 39,053,filed September 3, 1935, now Patent No. 2,029,250, dated Jan. 28, i936.The I-beams t have coupled to the base flanges thereof ground workingtools ii. The construction, arrangement, manner of connecting,description and purpose of the tools ill will be found in our co-pendingapplication, Serial Number 24,553, filed June 1, 1935,

The body l is suspended, supported and vertically adjusted by acushioned combined suspen sion supporting and traction structure, inaccordance with this invention, arranged at and connected to each sidethereof. The structure includes a bushing I8 mounted in a channel iron9, a hanger IS, a means 20 for anchoring the hanger I 9 to body 1, andadjusting mechanism 2 i, for the hanger and a traction wheel 22 of thepneumatic 5 type carried by the hanger IS. The bushing i8 is anchored inan opening H. The hanger i9 is of angle form and includes anintermediate part 22 and a pair of oppositely extending end parts 23, 24disposed at right angles to part 22. The parts 23, 24 extend inwardlyand outwardly respectively relative to the ends of part 22. The part 22is passed through the bushing l8 and is disposed parallel to the innerface of the web l2 of the forward I-beam of the set. The means consistsof an apertured plate 25 positioned against the inner face of web l2 anda yoke 26. The latter surrounds leg 23, extends through openings-l3 andcarries clamping nuts 26 which abut the forward face of web l2. Theadjusting 20 mechanism 2! for the hanger H) which provides for elevatingand lowering body 1 consists of a coupling member 21 which is connectedto the lower or rear portion of leg 22 and formed with an upstandingshank 28,-.an upstanding link 29 connected at its lower end, as at 30,to shank 28, a bar 3| secured to the outer face of link 29 and having anoffset upper portion 32, a lever 33 passing between the portion 32 andlink 29 and pivotally connected intermediate its ends, as at 3%, to saidportion 32 and link 29, a standard 35 anchored at its lower end to achannel 9, as at 36, and extending above body 7. The standard 38 mergesat its upper end into a rearwardly extending downwardly curved rack 37of quadrant shape, anchored at its lower end, as at 38, to that channeliron 9 to which the standard 35 is secured. The lever 33 is providedwith the usual dog or pawl and lever mechanism 39 which associates withthe rack 31 to releasably retain the hanger I9 in its adjusted position.The traction wheel 22 is revolubly mounted on the leg 24 of hanger I9and is retained thereon by a nut or cap 40. When the leg 22* of hangerI9 is elevated or lowered the body I is shifted in a like manner andsuspended from hanger IS in the position to which it has been adjusted.The wheels 22 constitute a cushioned supporting means for body I. Theanchoring means 36 for standard 35 provides a pivot for the lower end oflever 33.

,The structure shownin Figure 6 relates to a modification of thecushioned combined suspen-- sion, supporting and traction structure, andin this connection the upper leg 4! of the hanger 42 is connected to theskeleton body of the mobile ground working device by a different meansthan that aforesaid. The said different means includes a sleeve 44formed intermediate its ends with a threaded shank 45 which extendsthrough an opening 46 formed in the web 41 of the forward I-beam 48 ofbody 43. The sleeve 44 extends through opening II in a channel iron 9.The leg 4| extends inwardly of the inner end of sleeve 44 and isprovided with a stop pin 49. A clamping nut 50 is carried by shank 45and abuts the forward face of web 41. Otherwise than that .as stated themodified form of suspension, supporting and traction structure shown inFigure 6 would be the same as that shown in Figures 2 to 4.
